AI Security Review

scanned 2h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall downloads an unchecked platform binary and immediately runs its agent-hook installer. This mutates external Codex and Claude Code integration surfaces without a user command.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm installation

Impact

A release-hosted replacement binary can execute and install hooks into Codex and Claude Code during dependency installation.

Mechanism

remote binary download followed by postinstall agent-hook execution

Policy narrative

Installing the package invokes a lifecycle script that downloads a platform executable into vendor/ and runs it with --install-agent-hooks. The package provides no checksum or signature verification, while its documentation says this installs Codex and Claude Code hooks. Thus a remote release artifact is granted install-time execution and can alter external AI-agent control surfaces without an explicit user setup command.

Rationale

The concrete postinstall chain downloads and executes an unverified remote binary, then installs hooks for third-party AI agents. This meets the block threshold for unconsented install-time mutation of a foreign/broad AI-agent control surface.
